An organic light emitting diode display includes a substrate including a display region displaying an image and a peripheral region surrounding the display region, a plurality of pad wires formed in the peripheral region of the substrate, and a plurality of bumps formed between the plurality of pad wires. The organic light emitting diode display blocks or relieves impact which is generated when a temporary upper protective film is half-cut and applied to a plurality of pad wires or an insulating layer by forming a plurality of bumps between the plurality of pad wires, thus preventing a damage to the pad wires or the insulating layer.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A manufacturing method of an organic light emitting diode display, comprising: forming a plurality of pad wires in a peripheral region of a substrate, wherein the substrate includes a display region displaying an image and the peripheral region surrounding the display region; forming an insulating layer on the substrate and the plurality of pad wires; forming a protective layer covering the display region on the insulating layer; forming a plurality of bumps between the plurality of respective pad wires, wherein the plurality of bumps is formed in the peripheral region on the insulating layer; and attaching a temporary upper protective film onto the plurality of pad wires and bumps.
2. The manufacturing method of an organic light emitting diode display of claim 1 , wherein: one or more bumps are respectively formed in spaces between adjacent pad wires.
3. The manufacturing method of an organic light emitting diode display of claim 1 , wherein: one or more bumps are respectively formed only in some spaces between adjacent pad wires.
4. The manufacturing method of an organic light emitting diode display of claim 1 , further comprising: half-cutting a peripheral portion of the temporary upper protective film by using a cutter.
5. The manufacturing method of an organic light emitting diode display of claim 4 , further comprising: removing the temporary upper protective film.
